Answer:
66
Step-by-step explanation:
11 times 6 = 66
Given:
<span>random sample of 520 adults
mean was 150
standard deviation was 4.5.
reported with a 95% confidence level, and the confidence interval for the study was 150 ± 0.39.
The range of </span><span>values that shows the confidence interval for the study is </span><span>149.61 to 150.39
150 + 0.39 = 150.39
150 - 0.39 = 149.61</span>
(f+g)(x) is 3x^2 + 3x/2 - 9
(f+g)(x)=f(x)+g(x)=x/2-3+3x^2+x-6= 3x^2 + 3x/2- 9
